印染物化污泥危废鉴别实例研究

Case Study on Identification of Hazardous Waste from Printing and Dyeing sludge

印染行业属高耗能、高耗水、高污染行业,其污染主要以废水污染为主。随着印染废水治理强度的加大,以及国家对固体废物、尤其是危险废物监管力度的加强,印染废水治理产生的二次污染物-印染污泥也引起社会的高度关注和监管部门的足够重视,尤其是对于印染物化污泥的定性,也存在许多不同的观点,因此印染物化污泥的危废鉴别也成为许多印染企业面临的共同课题。本次印染物化污泥危废鉴别,方案合理、内容全面、过程规范、数据充实,对同类项目具有较好的借鉴意义。

Printing and dyeing industry is characterized by high energy consumption,high water consumption,high pollution.Its pollution is mainly wastewater pollution.With straightened regulations on printing and dyeing wastewater treatment,as well as the state's intensified management on solid waste,especially hazardous waste,printing and dyeing wastewater treatment,printing and dyeing sludge of secondary pollutants also received more attentions from the society.The qualitative study of printing and dyeing and chemical sludge have faced many different points of views.Therefore,identification of hazardous waste of printing and dyeing sludge has become a common problem faced by many printing and dyeing enterprises.The identification of hazardous waste of printing and dyeing chemical sludge has reasonable scheme,comprehensive content,standard process and abundant data,which has good reference significance for similar projects.
